Understanding the Mechanics of Electric and Hybrid Cars.

Hybrid electric vehicles (HEVs) use an internal combustion engine and electric motors to run, making them a cross between a gasoline car and an electric car. There are three main types of HEVs: mild hybrids, full hybrids, and plug-in hybrids (PHEVs). PHEVs are more expensive but produce lower emissions because they can run solely on electricity for longer. HEVs use an internal combustion engine and battery-powered electric motor to achieve high fuel economy and low emissions. Hybrid cars do not need to be charged, but plug-in hybrid vehicles can be charged with charging equipment.
